Am J Gastroenterol:结肠镜更佳检查时长9分钟(Hampshire结肠镜登记研究)

2014-02-04 MedSci MedSci原创

美国一项最新研究提示,结肠镜检查时间的长短与结肠息肉、腺瘤、锯齿状息肉检出率有关。研究者指出,有充分证据支持将结肠镜检查的标准时长定为 9 min,因为此时结肠腺瘤和息肉的检出率最高。研究者回顾性分析了 7996 次结肠镜检查相关数据,参与结肠镜检查的 42 名内镜医师的技术水平存在一定差异。结果显示,正常的结肠镜检查时长为3 min~10 min以上,中位时长多为8 min。目前建议,结肠镜检查

美国一项最新研究提示,结肠镜检查时间的长短与结肠息肉、腺瘤、锯齿状息肉检出率有关。研究者指出,有充分证据支持将结肠镜检查的标准时长定为 9 min,因为此时结肠腺瘤和息肉的检出率最高。



研究者回顾性分析了 7996 次结肠镜检查相关数据,参与结肠镜检查的 42 名内镜医师的技术水平存在一定差异。结果显示,正常的结肠镜检查时长为3 min~10 min以上,中位时长多为8 min。目前建议,结肠镜检查时长为 6~10 min。

研究者发现,中位检查时长为9 min 时,结肠腺瘤和息肉的检出率最高;检查时长为 8 min 时,锯齿状息肉的检出率最高(10.2%),检查时长为 9 min 时,锯齿状息肉检出率也处于较高水平(9.5%)。

在 检查时长超过 6 min 时,每延长1 min,结肠腺瘤和锯齿状息肉的检出率分别提高50%和77%,检查时长为 9 min 时患者获益最大。据估计,当以 9 min 作为结肠镜最短检查时长时,可将结肠腺瘤和锯齿状息肉的检查率分别提高 3.8% 和2.4%,其中结肠锯齿状息肉的检出率改善幅度将近 30%。

第二代结肠胶囊内镜(CCE-2)“挑战”传统结肠镜

  结肠胶囊内镜(CCE)是一种无需镇静、镇痛和肠道注气即可完成结肠黏膜观察的新型非侵入性内镜技术。为了提高结肠息肉的检出敏感性,有学者在第一代CCE系统基础上开发了第二代结肠胶囊内镜(CCE-2)。近期,欧洲学者一项多中心、前瞻性、“头对头”对照研究显示,CCE-2对检出结肠息肉(不含微小息肉)有很高敏感性,CCE-2可能成为结肠检查的有效工具。文章发表于9月《消化内镜》(Gastrointes

Gastroenterology:10%的肿瘤性息肉可能未被完全切除

  美国White River Junction退伍军人医疗中心的Heiko Pohl博士及其同事在《胃肠病学》(Gastroenterology)1月刊上报告称,在1,427例接受结肠镜检查的病例系列中,大约10%的直径介于5~20 mm的肿瘤性息肉未被完全切除。   在这项名为“完全腺瘤切除(CARE)”的研究中,Pohl博士及其同事对在这两家大型学术性医疗机构接受门诊结肠镜检查的年龄介于4

仅接受一次软式乙状结肠镜筛查预防结直肠癌的多中心随机对照试验

     背景:      结直肠癌是全球第三大最常见的癌症,死亡率很高。我们假设,55岁至64岁人群仅进行1次软式乙状结肠镜检查可明显降低结直肠癌的发病率和死亡率。     方法:      在英国14个中心进行随机对

DDW 2013:结肠镜退镜的更佳时间

  在5月18日至5月21日召开的美国消化疾病周上,来自美国斯坦福大学医学系胃肠病与肝病科的研究人员Kumar发表题为《评价结肠镜退镜的最佳时间:3分钟退镜与6分钟退镜的前瞻性随机比较》的论文。根据一项观察性研究的结果推荐6分钟为结肠镜筛查的最小退镜时间,这已成为实质上的处理标准。但6分钟的退镜时间仍有争议,没有用标准方法与其它退镜时间进行比较。在接受结肠镜检查的患者中进行一项对3分钟退镜与6分钟

GIE:注水结肠镜改善有盆腹部手术史患者的结肠镜检查

目前,结肠镜广泛应用于结直肠疾病的筛查和治疗。传统的结肠镜检查向肠腔注入空气以便检查,但可能导致结肠过度扩张,并增加了肠镜医生操作难度和患者的不适。有研究表明,以注水代替注气可避免结肠过度延长,显著降低患者腹痛评分,提高到达盲肠末端的成功率。 来自于西安第四军医大学西京医院的潘阳林教授等进行了一项前瞻性单盲随机对照研究。结果表明,对于中国曾有腹部或者盆腔手术史的患者,与注气结肠镜组相比,注水结肠
